 **Torque** provides information on the force applied by the motor, provided in kg/cm or oz/in. This represents the weight that can be held on a lever at that much distance from the shaft, with each doubling of distance resulting in a halving of the supported weight.  **Torque** provides information on the force applied by the motor, provided in kg/cm or oz/in.

 Frequent applications of servomotors are robotics, such as robotic arms, where rotational accuracy is valued. This also makes servo motors a good fit for applications such as CNC machines, 3D printers, and other automated manufacturing. Frequent applications of servomotors are robotics, such as robotic arms, where rotational accuracy is valued.

-This built-in feedback system can also be used to measure rotations, such as its use in the vBow, where it is used to measure bow speed, angle, and placement on the instrument. As mentioned above, the gear system used in a servo motor allows for a constant level of torque at all it’s rotation speeds, which may be desirable. +This built-in feedback system can also be used to measure rotations, such as its use in the vBow (Nichols, 2002), where it is used to measure bow speed, angle, and placement on the instrument.
